Arc Fault circuit breakers and Inverters.

[Saggys]

In the spirit of following the 2011 NEC I will be installing AFCI breakers where required in my service panel. Just curious if anyone has had any nuisance trips with inverter or generator power?

I've heard any "brushed" appliance will set them off. Vacuum cleaners, blenders, plug-in drills. Contractor has a pretty much standing offer, you rent the breakers till after inspection, and then you swap them out. Sure, they might stop a couple fires a year, but that's what smoke alarms are for. I also have to disable a 24/7 ventilator, since new houses are so tight, now they don't breathe, and you have to install a fan. Off grid in the winter, I don't have the power to feed a fan. I can open a window. And with a "outside air intake" for my heater, I can't even rely on that to do air exchanges. Bureaucrats & Nanny State - bleah.

They are only required to be used in bedroom receptacle circuits.

I guess I will need to move the Mig welder out of the bedroom.
She hates when I weld in there anyway. Something to do with odors and bright lights while she is trying to sleep.

Sunking,

The 2005 Code lists bedrooms, 2008 lists familly rooms, dining rooms, living rooms, parlors, libraries, dens, bedrooms, sunrooms, recreation rooms, closets, hallways or similiar rooms or areas. I do not have my 2011 code book handy, it's at work but 2011 code breaks it down to something like everywhere except kitchens and bathrooms, basically anywhere that is required to have GFCI protection.
I agree, over priced and over regulated.

You are right, I had to go look. My bad, but residential is not my everyday thing. Here in Dallas 5 county region is still on 2005 cycle and Arc Fault Breakers are admended out so they are not required due to the expense. I was a member of 2002 and 2005 code cycle panel 9 and AFCI was hotly debated as it was mostly introduced by one manufacture (the only one that made them at the time) and supported by Fire departments and insurance interest.
